Understanding Oracle JSON Output Group by Key ===================================================== In this article, we’ll explore how to achieve the same level of grouping as in SQL Server when outputting data from Oracle in JSON format. Introduction to JSON Output in Oracle Oracle provides a built-in JSON function that allows us to generate JSON output from our queries. This feature is particularly useful for generating JSON responses for web applications or APIs. One of the key benefits of using JSON output is its ability to nest and group data, which can be easier to work with than traditional CSV or table formats.

Weak References in Objective-C Properties In Objective-C, properties can have one of two attributes: strong or weak. The primary purpose of these attributes is to manage the memory usage and lifetime of an object. In this blog post, we will delve into the differences between strong and weak references in Objective-C properties. Introduction to Objective-C Properties Before diving into the details of weak references, it’s essential to understand how properties work in Objective-C.

Applying Shift(x) to a Pandas DataFrame Column using Rolling Window When working with pandas DataFrames, performing arithmetic operations on columns can be straightforward. However, when dealing with cumulative sums or shifting values within a window, the available methods are more limited compared to traditional arithmetic operations. In this article, we’ll explore an efficient way to apply shift(x) to a pandas DataFrame column using the rolling() method with a specified window size (n).

Understanding Modal Dismiss and Notification-Based Communication Between View Controllers In iOS development, dismissModalViewControllerAnimated: is a common method used to dismiss modally presented view controllers. However, when working with multiple view controller classes and the need for inter-view controller communication, things can become more complex. In this article, we’ll delve into how to dismiss a modal view controller from another view controller class using notification-based communication.
